Abstract: Petroleum geologists have known for 50
years that global oil production would "peak" and begin its
inevitable decline within a decade of the year 2000. Moreover, no renewable energy systems have
the potential to generate more than a tiny fraction of the power now being
generated by fossil fuels.
In short, the end of oil signals the end of civilization, as we know it.
